EXPERIMENTAL STUDIES ON THE DEVELOPMENT OF RESIDUAL STOMACH CANCER
-COMPARISON OF BILLROTH I AND BILLROTH II-
The effects of duodenogastric reflex on the development of residual stomach cancer and cell proliferation kinetics were investigated in Wistar rats. Billroth II resection (B-II group) was performed on 24 rats and Billroth I resection (B-I group) was performed on 22 rats. The incidence of cancer in the B-II group was 20.8%, though no cancer was noted in the B-I group. The incidences of the pseudopyloric gland, dilated gland and gastritis cystica profunda in the B-II group were significantly higher than those in the B-I group. The degree of mucosal atrophy was greater in the B-II group than in the B-I group. The stomal area in the B-II group had expansion of proliferative zone as well as increased S-phase duration and turn over time, compared with those in the B-I group. The sequence of histological and proliferative events associated with duodenogastric reflux suggests that the residual stomach in the B-II group is susceptible to the development of cancer.
